GAS H EATER-OR STOVE.

SPECIFICATION forming part of Letters Patent No. 745,287, dated November 24, 1903. Applioationfiled February 6, 1903 Serial No. 142,129. (No model.)

To all whom it may concern:

Be it known that I, HENRY MAYTROTT, a citizen of the United States, residing at the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Gas Heaters orStoves, of

. which the following is a specification.

v without smell or smoke.

My in vention relates toagas heater or stove of simple inexpensive construction and of maximum radiation, with the object of effecting substantially perfect combustion with a minimum consumption of gas.

In carrying out my invention and in combination with a cylindrical metal case or drum I employ a gas and air burner ofpeculiar form and a deflector-plate above the burner and beneath which the gas and air burn as a spread or disk-like flame covering approximately the area of the deflector-plate and.

producing substantially perfect combustion before entering the gas-pipe to be commingled with the gas, and the entrance of the air is flector-plate andthe inner surface of the cylindrical case or drum there is an annular opening for the heated air.

' In the drawings, Figure 1 is a vertical section illustrating my improved gas heater or stove. Fig. 2 is a sectional plan at a; a: of Fig. 2, and Fig. 3 is a vertical section at the upper end of the gas-pipe and through the burner structure in larger size.

or represents the cylindrical case or drum, preferably of sheet metal and provided near its lower end with perforations 2 and near its upper end with perforations 3, which perforations may be given any form or desired outline.

12 represents a sheet-metal base with aflange receiving the lower end of the cylindrical case or drum or and with supporting-legs b secured thereto.

0 represents a sheet-metal top having perforations 4: in the central portion,'and d d are bolt tie-rods that-pass through the top 0 within the cylindrical case or drum and through The air is heated.

the sheet-metal base I) to securely connect the case or drum, the base, and the top into a permanent structure and apply tension thereto.

Within the cylindrical case or drum and rising from the central portion of the base is a pipe-standard e. This is secured to the base inany desired manner, and from the lower end of said pipe-standard extends a supplypipe 6' in a horizontal direction. through the sheet-metal base I), and in this pipe there is a gas-cock 5, controlling the supply of gas to the burner. At the upper end of the pipestandard 6 there is a coupling 6. Asheetmetal or Bunsen tube f is connected at its lower end to a coupling part that screws upon the coupling 6 and in which there is a small opening above the larger opening in the coupling 6.

In the base of the tube f there are perforations 7 for admitting air to be mixed with the gas that rises through the pipe-standard e and the couplings. Surrounding the smaller portion of the tube f there is an annular shield g in the form of an inverted cup, the lower portion or skirt of which surrounds the perforations 7. The top part of the Bunsen tube is made with a horizontal imperforate portion f and with an inclined portion 8, having perforations.

Within the cylindrical case or drum (7. is a deflector-plate h of appreciably less diameter. thanthe inner portion of said case or drum. This deflector-plate is preferably convex in form and secured at the central portion by a screw 9 to the imperforate center of the Bunsen-burner tube, so that said plate is supported directly upon said tube and the pipe-standard e. In the operation of the structure gas is suppliedin a regulatable quantity through the gas-cock 5, supply-pipe e, pipe-standard e, and air entering by the perforations 2 within the drum passes in through the perforations 7 of the Bunsen-burner structure in liberal quantities and co'mmingles with the gas' passing upward, so that the tube f becomes a mixing-chamber. The gas strikes with force against the under surface of the imperforate top f and is deflected through I00 the perforations of the part 8, around which the gas and air burn as a spread or disk-like I emerging through the perforations in the part 8. A very hotblue-red flame is in this manner produced, the size of which is alone con trolled by the quantity of gas passing in through the pipes to be consumed and the air r that mixes therewith, it being a fact that the liberal openings provided make it possible for as much air to be com mingled with the gas as can be taken up thereby. Consequently a flame in which there is substantially perfect combustion is produced, air in the case or drum above the deflector-plate his heated, and a large proportion of the air that enters through the lower perforations 2 passes up the inside of'the case or drum in the ann ular space between the said deflector-plate and drum, is

highly heated in transit, and passes out through the openings 3 or through the openings 4 in the sheet-metal top 0 into an apartment to heat the same.

I claim as my invention 1. Agas heater orstove, comprising a tubular cylindrical case or drum having perforations at the respective ends, a separable base for supporting the same, a perforated sepa- 5 rable top, means within and longitudinally of 5 necting the top and the base to hold the case or drum in position, a horizontally-placed deflector-plate within said case or drum and of smaller diameter than the interior thereof so as to leave an annular space between the parts,a central pipe-standard passing through the base, and a pipe connected therewith for supplying regulatable quantities of gas, a gas and air burner at the upper end of said standard, and means for connecting the deflectorplate to said burner.

3. A gas heater or stove comprising a base and supporting-legs, a cylindrical case or drum rising therefrom, a perforated top and means for connecting the top and the base to hold the case or drum in position, a deflectorplate within said case or drum and of smaller diameter than the interior thereof so as to leave an annular space between the parts,'a

central pipe-standard and a pipe connected therewith for supplying regulatable quantities of gas, a gas and air burner at the upper end of said standard, means for connecting the deflector-plate to said burner, there being openings in said burner for the entrance of air to commingle with the gas, and a shield covering and protecting said openings, andan inclined portion having perforations at the upper end of said burner beneath said de- Hector-plate.

4:. In a gas heater or stove, a burner comprising a tubular portion with openings for air near the base, an imperforate upper end, an inclined portion having perforations between said end and tube and through which commingled air and gas pass to be burned, and a deflectorplate directly above the burner, so that a downward and outwardly extending disk-like flame is produced, substantially as set forth.

5. In a gas heater or stove, a burner comprising'a tubular portion with openings for air near the base, an imperforate upper end, an inclined portion having perforations between said end and tube and inclined to a vertical plane, and through which commingled air and gas to be burned pass, so that a downward and outwardly extending disklike flame is produced, and a shield of in verted-cup form surrounding the tubular part of said burner and covering and protecting the air-apertures.

6. In a gas heater or stove, a burner comprising a tubular portion with openings for air near the base, an imperforate upper end, an inclined portion having perforations between said end and tube and inclined to a vertical plane and through which commingled air and gas to be burned pass, and a deflector-plate having a recessed center directly above the burner so that the horizontal part of the said plate is appreciably above the burner so that a downward and outwardly ex tending disk-like flame is produced, and a shield of inverted-cup form surrounding the tubular part of said burner and covering and protecting the air-apertures.

7. In a gas heater or stove, a burner comprising a tubular portion with openings for air near the base, an imperforate upper end, an inclined or flaring portion between said end and the tubular portion and having perforations therein that are inclined to a vertical plane and through which commingled air and gas pass to be burned, so that a downward and outwardly extending disk-like flame of substantially even thickness is produced.

Signed by me this 3d day of February, 1903.
